f'nomahgand State "i @regenf have "invented yimprovenets" iir'devfices forclamlpirig "and holding ,wire lesbies-aat are usearferfpuul ing stumps;

One obj ect of" the' iiivention 'is to l Iprvide 'a device Y"forfgri pi'ir'g andhofl'dlng "wire cable, f that is simple infcnstruct'ion and Operation, that allegri@tHe-"cable "seeurely pulling the stumps, but partvof'ftheapparatus is 'Pnfot' lierei'h "described iin detail velopirglapparatus. fr

The invention consists in thefliovel'fioustruction, adaptation aifdlic'mbination of parts, as will be more clearly/hereinafter described and claimed.

ile-'31 is a somewhat diagrammatic view inleva" tion of this device as it may appear when in use; Fig. 2 is a view with the top frame plate removed, showing the cable gripping devices partly in plan and partly in cross' section; Fig. 3 is a View in side elevation of the device shown in Fig. 2; and Fig. 4

i* described in a general way as being ene term et apparatus fer developing power fwith "which Athe cable grip l herein disclosed m'ay'bealdvaiitagously used.

Therod 10 terminates in a lixedly mountfjbody 11 and the" cable gripping device comprises two arms12tl`1at'are secured by 'boltslfto-"the'opposite parallel sides of the body 1,1 andvextend orwardlyin upwardly inclined :divergiiig relation 'oiro-pposite sides of two plates 14 and 15` thatare rigidly secured to each ether-"in spaced'apart relation bypins Yir-bolts 1'6. f

Disposed between the lplates 14' and 15 'are Nparall`el'with the piston rod`10 in substantial alinenient therewith;andare provided on their "inner 'edges with *longitudinally exe 'teirding'igrooves 19'or the reception 'of the cable"20, fTl'ie-grooves" 19 are corrugated, as indicated at 21,' to: insure a "better gripp'rng emit-'act' iwivth, the twisted wirel `cable 20L The :gripping 'awsv "17 and 1Sfa`rev provided lo'nthe 'edgesoppsite thegrooves 19 with recessedportions'f22, that are adapted for thereceiption' o fjcam surfaces on the efnds of lever `arnfisf2'4 that :arepivotally mounted 'onf' pins-26 that extend through the Aplates14"aialfil'. i

The lever "lar's "24 and "-25 extend outi'wai'dly ftlirougli bifurcjated portions 27 4"in theAVT eiids 'of "therar'm's "V12, and faire provided at their outer extremities with pins 28.

' pihs 26 are heldi'nfV position lby a long Iflie'y"'29 that extends through both of such pins above the plate 14 and by two short keys 30 that extend through the pins 26 below the plate 14 and are secured to such plate by cap screws 31. p

The front ends of the arms 12 are rigidly secured in spaced apart relation by an upwardly arched bar 32 and a downwardly arched plate 33, the end 34 of the bar 32 passing downward through suitable holes in the extremities of the arms 12 and the ends of the plate 33, so that the arms 12, bar 32 and plate 33 are rigidly secured to`- gether to form a frame within which the cablegripping devices are loosely or floatingly disposed. i

The gripping jaws 17 and 18 are loosely held within the plates 14 and 15 by the pins 16 and lever arms 24 and 25. 4

:When a pull is exerted on the cable 2O in the directien indicated by the arrow A, the cams 2e will engage the recessed per1n arms 2% and 25 kengaging with the down turned ends 34 of the cross bar 32.

It is obvious that the greater the tension on the cable 20, the more tightly it will'be gripped by the jaws 17 and 18.

Thefcable 20 may bev secured directly to the stump that is being pulled, or it'` vmay be passed through a tackle block 35, as shownl in F ig. 1, and one end securedto -a fixed support, the tackle block being secured to the stump 36 by a short cable 37.

It is obvious that changes in the form of construction of the several parts `of this device may be made within the scopek of the following claims. L,

yThat I claim, and desire to protect by Letters Patent, is n 1. In a stump puller, a' cable, aframe, means to reciprocate said frame, anda gripper for said cable loosely arranged in said frame, said gripper including a pair of movable clamping jaws and pivoted actuating cam levers therefor, said levershaving their free ends arranged in the path of apart of said frame whereby said levers are swung to move said movable clamping jaws into clamping engagement with said cable when the frame is moved in one direction, said free ends of said levers being arranged in .the path of another part of said frame whereby said levers are swung'to release said jaws from said cable when the frame is moved in the opposite directiom 2. In a stump puller, a body having opposite flat sides, means to reciprocate said body, a pair of spaced arms rigidly fastened to the opposite flat sides'of said body and extending forwardly from the latter in spaced relation,

Copies of this patent may be vo'ntaiiieifor -jaws having their free ends five cents each,by addressing Washington,A D. (2.,y y.k i

oppositely bowed arch members vrigidly connecting the forward free ends of said arms, and a cable gripping device including a Vframe loosely disposed between said arch members, said cable gripping device including a pair of, spaced plates having a pair of gripping jaws loosely arranged therebetween, and cam levers pivotally mounted between said plates to vactuate said .clamping jaws, the opposite free ends of said cam levers being operatively connected to said arms whereby. movement of the body 'in lonefdirection Awill cause said levers tov Asite fiat faces, means to. reciprocate said body,-a pair of arms secured to the opposite ,fiat faces lof said body .and extending forwardly `from the latter in spaced relation,

the free ends of said arms being bifurcated,

van upper arch. member connecting the free ends of, said arms and extending through the latter, a lower oppositely bowed arch member .connectedvto the ends of the .upper arch memberbelow said arms, a ypair of spaced plates loosely `disposed'between said arch members, cable grippingjaws freely carriedfbetweensaidplates, and cam levers pivotedbetween said plates to move said extended throughthe bifurcations of said arms, substantially as described. l e
